In the event where we "merge" we duplicate the changes of the source script onto the newly cloned copy. This function will synchronize the compiled script results assuming that the scripts themselves are bound to the same key. This saves looking things up in the DDC. It returns true if successfully synchronized and false if not.
bool SynchronizeExecutablesWithCompilation ( const [UNiagaraScript](API\Plugins\Niagara\UNiagaraScript) * Script, const [TMap](API\Runtime\Core\Containers\TMap)< [FString](API\Runtime\Core\Containers\FString), [FString](API\Runtime\Core\Containers\FString) > & RenameMap )
